Class OCCTVertex

OpenCascade 中的顶点：内核自身的点形式，即边相接的角。库的其余部分使用普通的 [x, y, z] 点，因此这里的方法主要在两者之间转换：从点创建顶点，从顶点读回点，列出任意形状的顶点，以及将点投影到形状上。

constructor

new OCCTVertex(): OCCTVertex
Returns OCCTVertex

from

vertexFromXYZ

vertexFromXYZ(inputs: XYZDto): Promise<TopoDSVertexPointer>
由 x、y 和 z 值创建顶点。
Parameters
- inputs: XYZDto
  三个坐标
Returns Promise<TopoDSVertexPointer>
顶点
Example
```
const vertex = await bitbybit.occt.shapes.vertex.vertexFromXYZ({ x: 1, y: 2, z: 3 });
```
- Defined in bitbybit-docs.d.ts:45096

vertexFromPoint

vertexFromPoint(inputs: Bit.Inputs.OCCT.PointDto): Promise<TopoDSVertexPointer>
由普通的 [x, y, z] 点创建顶点，即内核自己的点。
Parameters
- inputs: Bit.Inputs.OCCT.PointDto
  以 [x, y, z] 表示的点
Returns Promise<TopoDSVertexPointer>
顶点
Example
```
const vertex = await bitbybit.occt.shapes.vertex.vertexFromPoint({ point: [1, 2, 3] });
```
- Defined in bitbybit-docs.d.ts:45109

verticesFromPoints

verticesFromPoints(
inputs: Bit.Inputs.OCCT.PointsDto,
): Promise<TopoDSVertexPointer[]>
为每个普通的 [x, y, z] 点创建一个顶点，即内核自己的点。
Parameters
- inputs: Bit.Inputs.OCCT.PointsDto
  点
Returns Promise<TopoDSVertexPointer[]>
每个点一个顶点，顺序相同
Example
```
const vertices = await bitbybit.occt.shapes.vertex.verticesFromPoints({ points: [[0, 0, 0], [1, 0, 0]] });
```
- Defined in bitbybit-docs.d.ts:45122

verticesCompoundFromPoints

verticesCompoundFromPoints(
inputs: Bit.Inputs.OCCT.PointsDto,
): Promise<TopoDSCompoundPointer>
为每个点创建一个顶点，并将它们打包成一个复合体，使整个点云可以作为一个形状绘制或变换。
Parameters
- inputs: Bit.Inputs.OCCT.PointsDto
  点
Returns Promise<TopoDSCompoundPointer>
每个点含一个顶点的复合体
Example
```
const cloud = await bitbybit.occt.shapes.vertex.verticesCompoundFromPoints({ points: [[0, 0, 0], [1, 0, 0], [0, 1, 0]] });
```
- Defined in bitbybit-docs.d.ts:45136

get

getVertices

getVertices(
inputs: ShapeDto<TopoDSShapePointer>,
): Promise<TopoDSVertexPointer[]>
按内核遍历的顺序列出形状的每个顶点。

顶点会为使用它的每个面和边重复，因此一个长方体列出 48 个顶点而不是 8 个角；要得到不重复的角，请将 getVerticesAsPoints 与 point.removeAllDuplicateVectors 配合使用。
Parameters
- inputs: ShapeDto<TopoDSShapePointer>
  形状
Returns Promise<TopoDSVertexPointer[]>
形状中找到的顶点
Example
```
const corners = await bitbybit.occt.shapes.vertex.getVertices({ shape: box });
```
- Defined in bitbybit-docs.d.ts:45153

getVerticesAsPoints

getVerticesAsPoints(inputs: ShapeDto<TopoDSShapePointer>): Promise<Point3[]>
按内核遍历的顺序，以普通的 [x, y, z] 点列出形状的每个顶点。

顶点会为使用它的每个面和边重复，因此一个长方体列出 48 个点而不是 8 个角；point.removeAllDuplicateVectors 可将它们缩减为不重复的点。
Parameters
- inputs: ShapeDto<TopoDSShapePointer>
  形状
Returns Promise<Point3[]>
顶点的点
Example
```
const corners = await bitbybit.occt.shapes.vertex.getVerticesAsPoints({ shape: box });
```
- Defined in bitbybit-docs.d.ts:45169

place

projectPoints

projectPoints(
inputs: ProjectPointsOnShapeDto<TopoDSShapePointer>,
): Promise<Point3[]>
沿某方向将点投射到形状上，并给出它们落到的点。

每个点沿 direction 恰好行进该向量的长度，因此它必须足够长以到达形状。当路径不止一次穿过形状时，projectionType 保留最近的命中、最远的、两者或全部；未命中的路径不给出任何东西。
Parameters
- inputs: ProjectPointsOnShapeDto<TopoDSShapePointer>
  点、形状、带长度的方向，以及要保留哪些命中点
Returns Promise<Point3[]>
投影后的点
Example
```
const onGround = await bitbybit.occt.shapes.vertex.projectPoints({
    points: [[0, 10, 0], [1, 10, 0]],
    shape: terrain,
    direction: [0, -20, 0],
    projectionType: Bit.Inputs.OCCT.pointProjectionTypeEnum.closest,
});
```
- Defined in bitbybit-docs.d.ts:45217

transform

verticesToPoints

verticesToPoints(inputs: ShapesDto<TopoDSVertexPointer>): Promise<Point3[]>
以普通的 [x, y, z] 点读取每个顶点的坐标。
Parameters
- inputs: ShapesDto<TopoDSVertexPointer>
  顶点
Returns Promise<Point3[]>
每个顶点一个点，顺序相同
Example
```
const points = await bitbybit.occt.shapes.vertex.verticesToPoints({ shapes: vertices });
```
- Defined in bitbybit-docs.d.ts:45182

vertexToPoint

vertexToPoint(inputs: ShapeDto<TopoDSVertexPointer>): Promise<Point3>
以普通的 [x, y, z] 点读取顶点的坐标。
Parameters
- inputs: ShapeDto<TopoDSVertexPointer>
  顶点
Returns Promise<Point3>
点
Example
```
const point = await bitbybit.occt.shapes.vertex.vertexToPoint({ shape: vertex });
```
- Defined in bitbybit-docs.d.ts:45195
